The housing 1 of the power distribution line plug A of the first embodiment is formed with a recessed portion 13 inserted into the connection portion 40 of the power supply-side wiring device (for example, a junction box BX, etc.) on the front side, and three inserts are protruded inside the recessed portion 13 1 5. As shown in 圊 1, the housing is composed of a main body 11 and a cover 12 made of synthetic resin, and the main body 11 and the cover 12 are box-shaped openings at the front, rear, and upper and lower sides, respectively. The interior of the main body 11 is divided into a front and rear installation space by a partition plate 20, and a concave portion 13 is formed by a front concave portion 14. The partition plate 20 is provided with three fixing grooves 16 for pressing three inserting pieces 15 for fixing, and inserting the inserting pieces 15 into the power supply side 16 for installation. In the recess 14, the front ends of the inserts 15 are parallel. Of permutations. Two partition walls 18 are formed in the longitudinal direction from the rear surface of the partition plate 20, and the front of the rear mounting chamber is divided into three regions. In this separated region, the rear end portion of the insert 15 is mounted.

Description of the invention (9) On the cover 12, corresponding to the partition 20 of the main body 11, a partition 43 is formed, and the joints between the fixing grooves 16 of the partitions 20 and 43 are formed in a concave-convex shape. That is, as shown in Fig. 2 (b), a step is formed between the fixing grooves 16 of the partition plates 20 and 34, and the respective concave portions and convex portions are exactly matched. In this way, in the part where the step is formed, the creepage distance between the power supply sides of the partitions 20 and 43 can be extended, and the insulation distance between the inserts 15 can be extended, and the body 11 can be absorbed by the step. Or the deformation of the cover 12 does not cause a gap between the joints, thereby reducing the occurrence of poor insulation. Each insert 15 is made of a flat plate-shaped conductive material. On the base ends of these insert pieces 15, the terminal piece 17a is folded into a single body, and a screw through-hole of the terminal screw 17b is provided. The terminal piece 17a and the terminal screw 17b constitute a terminal portion 17. Therefore, a three-core wire with a ground wire (for example, a wire with a cutting area of 2-3.5mm2 of vinyl insulated flexible (VCT) cable) 31 is crimped with a crimp terminal (not shown in the figure). The terminal screw 17 b is fixed to the terminal piece 17 a and is connected to the terminal portion 17. The end of the terminal piece 17a is provided with a clamping piece 17c whose front end is divided into two, corresponding to the clamping piece 17c. A flange protruding on the body 11 is pressed into a claw provided between the clamping pieces 17c, and is fixed by pressing.

If this is done, the protruding amount of the insert 15 is large, and the connection part 40 of the junction box "from the Γ power distribution line plug A _ can prevent the insert 15 as the ground electrode from being inserted 1 5 is separately connected to the connection part 40, that is, when the power distribution line plug A is connected to the connection part 40, the other blades 15 must be connected to the connection part 4 0 before connecting the blade 15 as a ground electrode, Conversely, when the power distribution line plug A is pulled out from the connection portion 40, the other insert pieces 15 are disconnected from the connection portion 40, and then the ground electrode piece 15 is removed. Therefore, even if there is a leakage, there is no electric shock. On the top, a non-slip clasp 28 capable of locking the connection state is provided when the connection part 40 of the junction box BX is inserted. The non-slip clasp 28 is made of a flexible synthetic resin or the like, and the front end has a horizontal In the direction of the protruding claws 30, two cross-shaped elastic pieces 32 of the l-shaped protrusions on the lower side of the central protrusion protrude from the main body 11 below the two elastic fixing legs 33.

The non-slip buckle 28 is mounted on the mounting portion 29 by first inserting the fixed leg 33 of the non-slip buckle 28 into the insertion hole 39, and then pressing the elastic piece 32 into the insertion recess 37, so that the rear end face thereof enters the insertion recess. The steps at the back of the 3 are locked, so that the front claws of the lower part of the fixing leg 3 3 are stuck on the opening edge inside the insertion hole 3 9, as shown by the circle 2, and fixed on the main body 11. In this embodiment, the gap 'from the rear end surface of the elastic sheet 32 to the front of the base of the fixed leg 33 is slightly larger than the gap between the stepped portion behind the insertion recess 37 and the opening edge on the front side of the insertion hole 39. Since the elastic piece 32 is larger than the stepped portion of the recessed portion 37 on the horizontal piece, elastic force is applied forward, and the fixed leg 33 is indeed caught. On the side surface of the casing 1 (the surface of the main body 11), the nameplates 45 and 46 indicating at least information necessary for electric wiring are attached. On one nameplate 45, the polarity of each blade 15 of the power distribution line plug A is written, and it is affixed to the surface of the recess 13 near the main body. "The other nameplate 46 is written on the specifications of the power distribution line plug A ' Into the surface near the mouth 21.

When the two halves are combined, there is no need to press the wire into the coupling direction, so the installation can be easily performed. From the display section, it is possible to know the electrical characteristics and applications of the power distribution plug, and the necessary information on the electrical wiring. When the core wire is connected to the crimp terminal, the installation work becomes easy. The effect of the eighth invention in the scope of the patent application is that a recess is formed in the front of the housing to match the connection part of the power distribution device on the receiving side. The front end of the plurality of inserts is arranged in the recess, and the electric wire is connected to its base end. A plurality of core wires are formed on the rear end portion of the housing to form a wire insertion opening for inserting the core wires of the wires, and a terminal piece is formed on the base end portion of each insert, and the core wires of the wires inserted from the wire insertion openings are electrically connected to it. These terminals are provided with terminal screws that clamp and connect the core wires, and an incorrect connection prevention portion is provided on the inner surface of the recessed portion to prevent reverse connection or connection with the connection portion of a wiring device with a different specification or purpose. At the same time, the shell and the wire insertion opening are made up of a pair of halves divided into two halves. Tension-relief pieces are provided on the inner walls of both sides of the wire insertion opening. The outer sheath is pressed in the joint direction, limiting the electric current caused by the force in the extension direction

Page 19 4 37J „_25 ______ V. Description of the invention (17) On the side of the housing, a diagram showing at least the electrical wiring information display section and the core wire length of the specified wire is shown, indicating that the core wire of the clamped wire is connected to the terminal On the chip, it can meet the needs of the value; there will be no reverse connection or connection with different specifications or uses of the connection part, which can prevent connection errors. At the same time, even if the diameter is different, it can also obtain a certain pulling force removal performance, which can act on the wire Pulling force. Information required for electrical wiring such as the pluggability or use of the power distribution line can be known from the display unit. When the core wire is connected, the installation work becomes easy. "Required part. When the rated wiring equipment is enlarged by the end Eliminate multiple electrical extra crimp terminals
